30 Claims. (Cl. 200-37) My invention relates in general to time controlled apparatus foroperatingvarious types of controllable equipment in accordance with a predetermined control program.

For convenience in description the invention will be considered more particularly with relation to its application to a radio receiver and the var ious descriptive term applied to theapparatus and the elements thereof will bechosen as connected with this application. It is understood that this invention is" not limited to an applica-' for use with controllable apparatus of various types A further object of my invention is to provide such a device in a compact, rugged form which not only is extremely flexible in adaptation and efllcient in operation, but also presents a pleasing v and unique appearance so as to add to the ornamental features of the structure to which it is adapted.

A still further object of my invention is to provide a time-controlled preselector device which is capable of setting to'a predetermined program in a rapid, positive, and simple manner.

Other objects and advantages of my invention will be apparent from the following description taken with the drawings, in which:

Fig. 12 is a diagrammatic illustration of a portion of the complete circuit-of the modification illustrated in Figs. 5 to 11, inclusive.

- In practicing my invention, I provide a preselector device having in combination, preselector mechanism, a time device, and a stationary cagelike formation of two sets of intercrossed but insulatingly separated electrical conductors, with one set of conductors adapted to be connected to the apparatus to be controlled thereby'and the otherset of conductors connected into an electrical circuit including the time device for operating' the controllable apparatus on a timed schedule. Interconnectors for the two sets of conductors are provided to complete a circuit through. corresponding preselected conductors and such interconnectorsfiare set to a predetermined schedule by the manually operated preselector mechanism including a pair of rotatable members having position indications therewith operatively connected withsaid interconnectors by rotatable and linearly moving means. One of the members is rotatable selectivelyfeither clockwise or counter-clockwise, with one rotational direction 01' movement acting to individually set the interconnectors to predetermined positions, and movement in the other direction causing all of the set interconnectors to be movedto non-connecting position.

In the specific embodiment of the invention, and referring initially to'Fig. 1, numeral I represents the case enclosing the preselector unit, shown here in front elevation. 'I'lus'preselector unit comprises a rotatable station index dial 2, having finger holes as 3, and a stop I, by which it may be rotated varying angular amounts, according to the finger hole chosen, similar to an from which the preselector and the balance of the system are arranged to intercept and translate. A rotatable time index dial lconcentric with and behind the station index dial 2 is arranged so that it may be observedand operated through a suitable slot 1 in the top of the easel. This time index dial, 6, is preferably notched and graduated in 56 quarter hour intervals, one for each 15 minutes of the;24 hours of a day, the notches being provided at the peripheral edge and the graduations being imprinted or impressed on the front face of the dial next to said edge. A roller 8 adjacent the periphery of the time index dial, and mounted on a pivoted crank arm 9, is urged by a spring In toward the periphery and will ride from notch to notch and seat in a notch when the dial comes to a standstill, thereby providing means for stopping the time index dial precisely at the quarter hour points.

In order that the mechanism operated by these index dials, as described hereinafter may not be thrown into disorder by improper manipulation of the dials, a mechanical interlock, "-42, is provided and arranged so that the time index dial 6 can be rotated only when the station index dial 2, is in neutral position. On exemplifiestion of an interlock is shown in Fig. 1, wherein station index dial 2 is illustrated at neutral position with a finger II on the crank arm I adjacent a notch I! in the station index dial but out of direct engagement therewith. As the roller 8 is on one end of said crank arm and finger II on the other end with the arm pivoted between said ends, said finger ll must register with its notch I! to permit any swinging of the arm. In this neutral position, finger II can enter notch I2 permitting roller 8 on the other end of crank arm 8 to be lifted and slide over the notches in a time dial 6. If station dial 2 is in any other position, finger II, hits the peripheral edge I! of station dial 2, the pivoted movement of the arm 9 is limited and the roller 8 cannot be lifted far enough to permit rotation of time, I. The same action prevents station dial! from being rotated unless the time dial" is accurately positioned with roller I at the bottom of one of the 96 notches of the time dial.

Although the preselector device of Figs. 1 to 4 normally acts automatically to control apparatus connected therewith, manual operation cin also be accomplished as illustrated in Figs. 1, 2 and 4.

Push-buttons ll for manual operation are provided extending through the front plate of the casefor the device with each supported by a comb-like conductor member I! connected to one side of the complete control circuit through aconductor l6 (Fig. 4). Each button I4 is directly supported on a shaft H which in turn is secured to a finger ll in the comb. Each of the fingers I is provided. with the remainder of the comb in a resilient material which tends to hold a -button I4 and its associated shaft II in idle position out of engagement with the contact member I9 (Fig. 2) in electrical contact with a corresponding station conductor or 'ring on the preselector as will be more fully understood hereinafter. A button I may be pressed "inwardly in the usual manner to complete the control circuit through the station conductor corresponding to such button so as to energize an operating L structure .for the radio receiver to which the prestation corresponding to the conductor. when the operator's finger is removed from the button II, the resiliency in the metal finger ll for that Particular button returns the shaft l1 and the button to normal idle position. with this portion of the preselector device it is possible to ad Just the receiver or other controllable apparatus to a desired control position entirely independent of any question of time. The automatic operation of the preselector device is, of course, accomplished in accordance with a predetermined time and function pattern.

Turning now to Fig. 2, the preselector mechanism embodies a clock, preferably of the self starting synchronous electric type, having hour and minute hands 20 and 2 I, respectively, face or dial I2, motor 23, and a suitable train of reduction gears, including interconnected gears 24, 25, 28, 21, I8, 28 and III. The motor 2! drives gear 24, and pinion 28 attached to gear 24 drives a floating gear 26. This in turn drives a pinion 21 by friction between gear 28 and pinion 21, with a spring ll acting on gear 28 maintaining suitable pressure to assure such friction. Pinion I] is attached to a shaft 31 which carries the minute hand II. For convenience the axis of this shaft will be designated the mainaxis for the apparatus. Y

The hour hand 20 is attached to a hollow shaft 83, which in turn is rotatably carried on shaft 32 and axially coincident therewith, and is driven through a 12 to 1 reduction gear chain comprising a pinion 11, gear 28, pinion 29 and gear 30 likewise attached to shaft 33. The central shaft 32 isextended rearward through hollow shaft or bushing 38, and has attached to' it pinion 34 which, with gear 35, pinion I8, and gear I1, make up a 24 to '1 reduction system between a contact making hour hand SI and a contact ma'king min-- ute hand 0. Gear 31 is attached to the hollow shaft 80 and this inturn has attached to it the contact making hour hand 30. The contact making minute hand N is attached to the central shaft 82, and a knob M on shaft 32 provides for rotating said shaft for setting the clock. The

contact making hour hand II carries at its outer successive time busses or conductors as 43, at

end a brush 42 which is arranged to contact which is directed laterally in the direction of selector is connected and tune the receiver to a rotation so as to mount a flexible brush 4! thereon which slopes radially outward and rearwardly to successively contact the ends of time busses or conductors ll (one at a time) as the hand rotata. The particular bus contacted in Fig. 3 is, for reference purposes identified bynumeral 0. The time busses are in anannular series insulated and spaced from each other, with the inner ends all substantially ending at the same radial distance from the center of rotation of the hands or There are preferably ninety-six of theftime busses, 43, evenly spaced in a complete circle, and, with the hand II geared to make one revolution in twenty-four hours, contact will thus be'maintained' by the brush with each bu fora period of approximately fifteen minutes at which time the brush snaps from one aiioaoo bus to-the next. It is understood that the number of busses or conductors 43v may vary in accordance with any desired time pattern.

The contact making minute hand 40 is similar in construction to the hour hand in that it also has a lateral brush 44 thereon which slopes radially outward and rearwardly. The brush 44 is arranged to make a contact of afew seconds duration every fifteen minutes with successive ones of four circumferentially spaced contact blocks, one of which is shown at 45. The brush 44, slides along a relatively fixed insulating strip .48 which slopes forwardly and inwardly, and then drops off of the end of this strip onto a contact block 45, closing a circuit under the control of these contacts every fifteen minutes. After a few seconds engagement determined by the length of the block 45, brush '44 drops off the end of the contact block 45, breaking the circuit with a quick break action, minimizing sparking. During the interval of contact of the brush 44 with contact block 45, a connection is made from block 46, through brush 44 and minute hand so to hour hand 39 and thence through brush 42 to a time bus as 43. The circuitthus formed may then be routed to select a broadcast station through the medium of an interconnector 41, which has previously been moved to a selecting position along the contacted time bus 43, to cross connect with a predetermined station bus as 48. An elevation of this arrangement is shownat the upper portion of Fig. 3 for one of the time busses, particularly designated as 43". The corresponding particular interconnector 41", comprises, as do the remaining interconnectors, a suitably formed metallic stamping arranged to slide longitudinally along the time bus 43", and to make contact between this bus and anyone of the plurality of circular station busses 48. The station busses or conductors 48 comprise spaced circular metallic rings electrically separate and concentric with the main axis of the apparatus. The station bussesor conductors aremolded or otherwise secured, in a cylinder C of insulating material. The interconnectors, slide along the time busses and provide means for setting up any desired system of cross connections between time. and station busses.

As previously explained, the hands .39 and 40 are illustrated inan axially aligned position in Fig. 2, while in Fig. 3, for purposes of clarity the 7 hands are moved so as to be spaced apart angularly and not with one directly behind the other.

A sectional view of the time and station bus arrangement is shown in Fig. 2, wherein at the bottom of the figure, one of the time busses 43 is shown overlying and in spaced relation to a plurality of station busses embedded in the insulative mounting C therefor. On time bus 43 is shown an interconnector 41 which slides along such bus for electrically cross connecting busses 43 and 48. Now it will be evident that by providing each time bus 43 including those designated particularly as 43' and 43", with a sliding interconnector such as 41", all considered as designated by the general reference character 41, for-each quarter hour of the twenty-four hour day, and by providing a station busor ring-like conductor 48, for each station .It is desired to receive, cross connections between selected time and station busses may be arranged to route a control circuit to select given'statioins at selected times. The preselector structure of the present invention may be connected with apparatus as described in my copending application, Serial No. v

146,359, for tuning the receiver to bring preselected stations at preselected intervals, or may be connected with any other suitable apparatus. A description will be given, however, of the mechanism whereby the station dial 2 and time dial, described originally in connection with Fig, 1, are utilized for setting the interconnectors to cross connect selected time and station busses or conductors.

Referring now to the right-hand center of Fig. 3 and upper right-hand corner of Fig. 2, there is shown one of the time busses 43 carrying a sliding interconnector 41. These elements are of course all of the same construction throughout. the preselector apparatus. Each interconnector has a projecting lug 43 arranged to lie in the path of a selector finger 50. This selector finger is preferably provided as an integral part of a larger member We of insulating material which is-slidably mounted in the groove 5|a. of a ring 5|. Ring 5| is in turn mounted upon and operatively connected with three lead screws, one of which is shown at 52, the other two screws being positioned either side of screw 62, parallel therewith, and at the same radial distance from the axis of shaft 32, thus carrying ring 5| with a three point support. Three pins 53, one for each lead screw, are carried in the ring and project radially of the ring and respectlve lead screws, into the respective thread grooves thereof and thus provide for moving the ring longitudinally or in an axial direction when the lead screws are rotated. Pinions, as 54, connect the three lead screws 52 with a gear 55, so that the three lead screws rotate in unison. "It will be evident that clockwise rotation of gear 55 will cause counter-clockwise rotation of the three associated lead screws 52, and that this will cause linear motion of ring 5|, moving it to the left from the position shown in Fig. 2. (The directions of rotation are specified viewing the apparatus from what is here termed the front, which is at the left in Fig. 2.) Ring 5| carries with it selector finger 50, so if ring 5| is moved to the left, finger 60 will engage lug 43 and move interconnector 41 to the left along the time bus 43, to bring it successively in contact with the plurality of station busses 48.

The station index dial 2, Figs. 1 and 2, is arranged to rotate about the main axis upon hub 51, Fig. 2. A pin 58 attached to and projecting rearwardly from dial 2, extends through an arcuate slot 59 in gear 55 in such a manner that when dial 2 is rotated from neutral position in a clockwise manner (viewed from the front) it carries with it gear 55, rotating the latter clockwise. The gear 55 rotates the lead screws 52 counter-clockwise, and moves ring 5| and selector finger 50 to the left. This in turn carries along to the left any interconnector 41 that lies in its path. Thus, if an operator inserts his finger in the hole marked in Fig. 1, which is the second hole in the dial, and rotates dial 2 clockwise untll stop 4 is reached, an interconnector will be moved along a time conductor until a corresponding station conductor 48 is reached. As illustrated herein, this would be the second station conductor from the right as viewed in Fig. 2.

In order to move a particular interconnector along a particular time conductor, selector flnger 50 (Fig. 2) may be placed opposite the desired interconnector by rotating time dial 6 which in turn rotates selector finger 50 through the medium of pin P, fixed to said dial and projecting rearwardly therefrom parallel to the main pin 81 carried in the preselector frame, and counter-clockwise rotation of dial 2- causes counter-clockwise rotation of gear 55 while gear 55 remains stationary against pin 61. In Fig. 1 portions of clock face 22, and dial 2 are broken away to show gear 55, slot 59 and pins 58 and 51. Gear 55 back of gear 55 may be seen through slot 59 as may also slot 66 in gear 65.

Returning to Fig. 2, a spiral spring 58 situated between the two parallel gears 55 and 65 has one end secured by a pin 59 to forward gear 55 when the clock reaches this particular quarter hour, a circuit as shown in Fig. 4 will be made through contact 45, hand 40 to hand 38, thence to a time conductor, as 43, andthence through the corresponding interconnector l1 thereon, to the selected station conductor 48. conductors are all individually connected into an energizing circuit, which in the case of a radio receiver may include a motor-driven tuner for operating the condenser or other tuning device for the receiver.

In order to place all interconnectors in a starting position preliminary to setting up a program of stations to be heard during a twenty-tour hour period, or any other period desired, the unit is arranged so that all interconnectors may be moved to the right until the end bus 48, which is a neutral bus, is reached. Referring to the lower left portion of Fig. 2, an insulating ring 80 is rotatably mounted in the peripheral groove Gla of a transversely or linearly movable ring 6| similar to ring 5|. The ring 6| rides upon three lead screws, one of which is shown at 82, the remaining two being 120 either side thereof parallel thereto and equally spaced from the main axis or shaft 32. Three pins 83, one for each lead screw, are secured in the ring BI and project radially of the grooved ring Bl andrespective lead screws 62 into the respective thread grooves of the screws, providing operative driving connection from the screws to the said ring, so that clockwise rotation of the screws 82 move ring SI, and, consequently ring 60 to the right. At their ends next to the operating dials, the three lead screws each have secured thereon, a pinion 84 which engages a single gear 85 rotatably mounted on hub 51. Rotation of gear 85 counter-clockwise (for clockwise rotation of the screws), is brought about by counter-clockwise rotation of station dial 2, Figs. 1 and 2, through the medium of pin 58, which engages gear 85 at one end of a slot 88 in said gear.

The construction as described thus provides for a neutral, normal or rest position for dial- '2 with the rearwardiy extending pin 58 carried thereby always positioned in arcuate slots 8! and O6 in the parallel pair of gears 55 and 65 respectively. At this rest position of station dial 2, pin 58, is engaged at opposite sides by end edges of the two said arcuate slots 58 and 68, one slot extending away from the pin in one direction and the other slot extendingaway from the pin in the opposite direction. When the station dial 2 rotates in one direction pin 58 moves freely in one slot but engages .the end edge of the other slot as a stop to cause that gear to rotate with the dial 2, and conversely, when the dial 2 is rotated in the opposite direction the gear just mentioned remains stationary and the other one The station and has its other end secured by pin ill to rearward gear 65. This spring 68 is arranged so that in neutral position of dial and gears, the dial,

gears, lead screws, rings, etc., are held in the positions shown in Fig.2, and are moved therefrom by rotation of dial 2 as already described. The spring returns all gears, lead screws and rings to the neutral or idle position, as shown, when dial 2 is released after rotation. In order to retard this return motion under spring tcnsion, 9. retarding mechanism such as a governor or escapement may be mounted upon one lead screw of each set of screws, as shown in Figs. 2 and 3. The particular escapement mechanism chosen for this disclosure may conveniently comprise an escapement wheel "H, with suitable peripheral teeth 12. The wheel a! is mounted rotatably upon the part to be retarded, in one instance on a cylindrical end portion of screw 62 for one set of lead screws, and in the other instance one. similar cylindrical end portion of screw 52 at the rear of the apparatus for the other set of lead screws. A ratchet wheel 13 is rigidly mounted upon the end of each such cylindrical portion, with a spring pawl 14 for the ratchet wheel pressing against the end face juxtaposed thereto of escapement wheel H as shown in Fig. 3. The end face provides radlal shoulders or notches 16 which the pawls will ride over when rotating in one direction but which will be engaged by the pawls when rotation is in the other direction. As shown, the screw 52 will, therefore, be relatively free to rotate in a counterwlockwise direction (as viewed in Fig. 3) but when rotating clockwise, the screw actuates the escapement wheel by virtue of engagement of the pawls against the notches of said wheel. An escapement rocker 'I'l overlies escapement wheel ll, being pivoted at 18 and having escapement teeth 19 to cause the rocker to teeter back and forth as escapement wheel H rotates. The rocker has adequate mass to obtain the desired amount of retarding effect upon the screw and connected parts. The escapement shown permits free forward motion, butretards the return motion, thereby minimizing rebound.

A modified embodiment of my invention is illustrated in Figs. 5 to 12, inclusive. This modified embodiment, similar to the structure in Figs. 1 to 4, inclusive, includes a preselector mechanism supported within a drawn housing 85 for mounting in any desired manner as a panel 88.

A clock 81 is supported within the preselector is rotated. In the specific disclosure, the arframe which includes a stationary annular ring 88 and a cup-shaped base I! spaced apart in fixed relation by a plurality of spacing posts 8| extending between the same. The clock 8! drives a pair of hands 92 and 93 for indicating the minutes and hours respectively on a clock face 94 at'the front of the preselector device. The clock 87 is a twelve-hour clock in the illustrated embodiment, but to assist in setting up the program over a twenty-four hour period, divisions for twenty-four hours are provided around the outside edge of the dial face. one clock-also acts to drive electrical contact mechanism as will be hereinafter described, to complete circuits through an interconnecting conductor system including a plurality of axially extending time conductors 96 corresponding in number'to fii teen-minute intervals over the twenty-four hours, and ring-shaped conductors 81 corresponding in numberto the desired number of broadcast stations which. it is desired to control. As previously explained, the entire me anism is describedas being applied to a radio receiver, but the station rings or conductors can also correspond to any'desire'd control function such as controlling the operation of a i'urnace, household appliances of many types, machinery, control equipment, and the like. The station rings are all embedded and insulatingly separated in an annular member 38 01' insulating material. Lugs 99 extend inwardly from such insulating memher from a connection withthe individual station rings for connecting the rings 21 into an operating circuit as will be explained. The time conductors are supported upon frame members Il of insulating material and when completely assembled comprise a substantially open annular cage-like structure. An electrical connection between a desired time conductor and station ring is accomplished by means of a. sliding interconnector-I02 similar to interconnector 41 in Figs. 2 and 3, on each time conductor 38.

The preselector device may be set up to operate according to a predetermined station and time pattern by setting the interconnectors I02 into a predetermined position relative to the time conductors and station rings, as explained with reference to the structure in Figs. 1 to 4, inclusive. This setting operation is accomplished in substantially the same manner as previously explained by means oi a selector finger I03 integral with an insulating ring I04 rotatably carried in a groove in the multi-part setting ring I00. The setting ring I 06 is identical with a cancelling ring It"! which also has an insulating ring 803 rotatably carried therein. The rings G63 and IN are linearly movable by means of three lead screws as G03 for the setting ring I08,

and a set of three identical'lead screws III for the cancelling ring I 07. Each 01' such rings III and i0! is connected with its respective set of three lead screws by means of lugs II 2 on discs carried rigidly on the rings intermediate the face of the ring and a cover plate H3 as shown particularly in Figs. 9 and 10. The lugs I-I2 ride in the spiral grooves on the lead screws. As shown at the top of Fig. 9, the lead screw Ill extends through an aperture. I I4 in the cancelling ring l0! so that movement oi the lead screw or movement of the ring I01 can be accomplished independently of the other. This same situation is true of the lead screws II I for the cancelling ring I01 which extend through corresponding apertures in the setting ring I03.

One set oi. lead screws as MS are rotated in a counter-clockwise direction upon rotation 01 a station dial "6 in a clockwise direction, while the'lead screws III are simultaneously rotated in a clockwise direction upon rotation of such station dial 8 in a counter-clockwise direction. The station dial H6 (Fig. 6) comprises an annular ring having a plurality of finger holes I I1 therein, and is fixedly secured on a support disc H8 by through the ring andinto a plurality'oi knobs M3 on the support disc. The support disc H0 isfixedly secured to a bushing I2I, and operatively connected to a pair or operating gears I22 and I23 for connection with the setting lead screws I00 and the cancelling lead screws III, respectively. This connection is accomplished by means or an integral lug I24 positioned in arcuate slots I23 and I2! in the gears I22 and I23, respectively, with such slots extending arcuately in opposite directions irom the lug I24 when the mechanism is in idle position. As shown in Fig. 11, slot I28 extends for more than 180 from T to T, while slot I21 extends for more than 180 from L to L. Adjacent ends of these slots are in engagement with the lug I24 when in idle position and such lug in engagement with an end of a slot causes movement of one gear or the other depending upon the direction of rotation of the station dial II6. A stop lug I28 inte-' gral with the cup-shaped member 89 likewise extends through the slots, in the twogears, I22 and I23, to limit the return 01 such gears after they have been operated. The position 0! the stop lug I28 corresponds with the position of the driving lug I24 when the mechanism is in idle position. The gears I22 and I23 are rotatably carried on the outside of a bushing shaft I29 as is shown in Fig. 9. I

The gear I22 is connected with the lead screws I08 through pinion gears I3I secured on the ends of each of such lead screws. Similar pinion gears I32 are secured on the ends oi. the lead lscrews III for engagement with the rotatable cancelling gear l23. As previously explained, the setting ring 404 is provided with a selector finger I03 for individually engaging one of the plurality of sliding interconnectors I02. The finger I03 is moved to a setting position in alignment with an interconnector I02 by means of rod connections l33 extending from the insulating ring I04, through the insulating cancelling ring 000 for fixed connection with a time gear I34 which in turn is secured to a bushing I36 in the general bushing assembly at the center of the mechanism, 1 means of a relatively wide pinion gear I3! which is directly driven by a thinner pinion gear I38 standing at an angle therewith, as shown in Fig. 9, so that the drive shaft for the gear I38 suitable securing means extending which includes a removable pin I39 with a finger knob I4! on the end thereof entirely clears the station dial lid in its rotary movement. The pin I28 fits into, and is keyed against rotary movement with relation to a socket I42 con-. nected with the gear E38. A pointer I43 integral .with a hook-shaped'arm I45 secured to the bushing I38, moves over the clock scale upon rotary movement of the time gear I34 by the knob III, and such pointer is aligned with the finger I03 so as to indicate on the clock face the particular quarter-hour-interconnector I02 with which the finger I03 is aligned.

With the finger I03 in a desired setting position the operator or the preselector device engages a desired indexed finger hole I" in the station dial H8 and rotates such dial clockwise until the operator's finger engages a stop shoulder I44 on a cover plate I46'irictionally retained in the base 89 (see top of Fig. 9). The rotary clockwise movement of the'station dial H6 is transmitted through the setting gear I22 and pinions I3I to rotate the lead screws I 09 in a I04 therein in a linear direction. distance of movement of the selector finger I03 The time gear I34 is rotated by is proportional to the rotary distance of movement of the dial III. This slides the selected Interconnected I02 to a station ring 91 indicated by the index tab marking carried in a finger hole I". This station correlation is, of course, predetermined in originally connecting up the preselector device to the radio receiver. In the particular structure illustrated in Figs. 5 to 12, inclusive, seven annular rings 01 are shown. The first ring at the right side 01' the device as shown in Fig. 9 is an "01! ring. 'When the Interconnector I02 is in the position illustrated in Fig. 9 it is simply in a neutral position so far as the control circuit is concerned. with the finger oi the operator in the first finger hole III with the index tab "01! (Fig. 6), however, thestation dial may be rotated clockwise and one of the ,interconnectors I02 set on the off" ring. This setting operation for any station or for "oil" position may be repeated for each of the quarter-hour intervals over the twentyfour hour period or the interconnectors may be set for only a relatively short period of time. The non-set interconnectors I02 may stand at neutral position on the insulating ring 00, which is the position of the interconnector in Fig. 9.

After an operator's finger is brought against the 1 shoulder I 04, the finger may be withdrawn from the hole III or the operators hand may simply follow the return movement of the station dial to idle position. The return movement is accomplished by a spiral spring I! connected at one end to the setting gear I22 and at the other end to the canceliing'gear I23. As the setting gear Is'moved in a clockwise direction, the spring is wound up or put under compression at the same time and this rorce tends to return the setting gear and station dial to idle position. The same procedure is followed with the cancelling gear I22 as will be hereinafter explained.

In order to prevent any possibility of jamming the mechanism of the device by careless operation. I provide interlocking mechanism between the support disc III through which the setting force is originally applied, and th'e' time gear Ill.- 'Ihe Jamming might occur if an attempt was made to rotate the selector finger I00 to ,a new setting when it was being linearly moved by rotation of the lead screws I00. The interlock mechanism is illustrated particularly in--Figs. 6 to 0. inclusive, and includes a pivoted lever I" pivotaliy supported In a bracket I" secured to the cup-shaped base member 80. The lever has a squared end III for seating in the correspondingly shaped notch I02 at the edge of the sup-' I02 and prevent rotary movement or the support disc III. A spring' I" acting on ,the lever Ill maintains the roller in engagement with the teeth I of the time gear. In order to prevent rotary movement of the time .gear I24 during the roller I53. The roller I03 remains seated intermediate two teeth I It as shown in Fig. 8 and also acts to stop the time gear directly on a timeinterval graduation, in this case, a fifteenminute interval.

At any time that it is desired to change the control program through thepresel'ector device, one connector I02, or all ninety-six connectors I02 may be collectively moved from a set position. between a predetermined time conductor 96 and station ring 91 by means 01' theinsulating ring I00. The insulating ring-I00 carried inthe clearing ring I01 has a diameter great enough so that it clear; the tips of the interconnectors. Counter-clockwise movement of the station dial Iii will cause rotation of the cancelling lead screws III to carry the clearing ring toward the right as viewed in Fig. 9. The interconnectors' I02 can be moved linearly toward the right in steps or the same length as they were moved toward the left, by clockwise movement of the station dial, depending upon the particular finger hole I I1 engaged. Normally, however, it is desired to move all of the connectors I02 which are in ,set position completely to the right to neutral position as they are illustrated in Fig. 9-

With a seven-finger hole configuration as providedin the illustrated embodiment, the finger hole furthest to the right lettered0fi is en-' gaged and the dial. is rotated counter-clockwise until the operators finger engages a shoulder I50 corresponding to shoulder I. The return spring I" which is secured at one end to the clearing gear I22 acts to return the station dial H0 and associated mechanism to idle position with the stop I28 in engagement with an end L or the slot I 21 in the cancelling gear I23.

The circuit connections through the preselector device are apparent from a consideration of Figs.

9 and 12. A circuit including a preselected time conductor 00 and a preselected corresponding conducting ring 01 is closed and opened through a movable contactor assembly unit I I0 including an arm I50 having a pivoted contact IOI at ,the top thereof which successively engages each of the time conductors 00 supported in the cagelike formation around the outside or the station rings 01. A spring I82 acts to maintain the contact Ill in engagement with the successive conductors. The contactor assembly unit I00, is insulatlngly supported on a bushing I "which like? wise carries a gear I 04 driven through a train the rotary movement, either clockwise or counter-clockwise, oi the support disc III, the notch I02 is moved out of alignment with the squared end III and the position and dimensions of these elements are such that the squared end will strike the periphery oi the'support' disc III and prevent pivotal movement oi the lever sufiicientiyM -rmitthe timegear Illtoberotatedpast of gears from driving gear I60 on a drive shaft II'I. Such shaft is,connected through gears with a pinion I00 on a stub shaft extending out of the clock 01. A spring washer IIIA permits gear I11 to slip with reference to shaft I01 ior .setting the clock. As a result the gears in the clock which would add materially to the load are cut out. The gearing intermediate the drive shaft I" and the contactor unit I" is such that the contact III completesa single revolution once every twenty-iour-hours while clock hands 02 and 03 make one revolution per hour and one revolution in, twelve hours, respectively. This period will. of course, vary in accordance with the total interval or time over which the preselector device is operated and can be made anvthing desired-for specific purposes. A stationary brush I'll is in continuous contact with the contactor unit Ill completing the circuit thereto as is apparent from the circuit diagram oi Fig. 12.

A circuit through a;predetermined routing including a station ring 01, an interconnect'or I02, and a time conductor 00, and-through the'contactor unit I58, is closed or opened directly through a switch and camstructure including a pair of contact arms I12 and I13 riding on two corresponding cams of insulating material indicated by the reference characters I14 and I16. The cams are carried on a rotatable shaft assembly including a gear I11 in engagement with the driving gear I68 with a ratio between the same such that the cam shaft assembly rotates through a complete cycle each fifteen-minute interval. As is apparent from the illustration in Fig. 5, the shoulder I18 on the small cam I14 is rearwardly in the cycle of rotation with reference to the shoulder I19 on the cam I16. When the contact arm I13 is riding on the periphery of cam I16, and the contact arm I12 is riding on the periphery of the cam I14, these arms are separated at the contact portions I8I so that the control circuit through the entire preselector device is open. However, as the cams reach the position shown in Fig. in their cycle of rotation, the contact arm I13 springs inwardly at the shoulder I19 of the cam I16 to cause engagement of the contact element IN. This closes a control circuit through the contact elements I8I and their corresponding contact arms I12 and I13, through the contactor unit I58 in engagement with'a time conductor 96, through such time conductor 98, the corresponding interconnector I02, and thence through a station ring 91, having a connection therefrom through the tuning apparatus for actually tuning the radio receiver. The electrical connection to the tuning apparatus is made through the plug I82 shown in Fig. 12. The circuit remains closed for a few seconds until such by clockwise rotation of the station dial I I6 with the operators finger in the finger-hole Il1 bearing the designation ofi (Fig. 6), a circuit may be closed through such ring'91 and the time conductor 96 upon which the particular interconnector is--slidable. The circuit also continues through the contactor and switch elements described above. This circuit may act to operate setting and cancelling mechanism from an operated position to an idle position as illustrated in Figs. 6 and 11. In order to retard this return movement, governor mechanism is provided on at least one lead screw in each of the two-sets of lead screws, one set including the lead screws I09, and

the other set the" lead screws I I I. The governor mechanism includes a gear I86 rotatably secured on the end of a lead screw as shown in Fig. 5 and a ratchetl81 concentric with the gear I86, but

fixedly secured on the end of a lead screw. The

gear I86 and ratchet I81 are connected together in one direction of rotation by a pawl I88 pivotal- 1y secured on the gear I86. The mounting of the pawl permits the ratchet I81 to pass the pawl on a setting or cancelling operation of a lead screw, but causes the pawl to engage the teeth of the ratchet I81 on the return movement from either of such operated positions. The gear I86 in turnis in mesh with a gear portion I89 on a rotatable member of governor unit I9I, rotatably secured on a fixed pivot pin I92 secured to the frame plate 88 of the preselector frame. An arcu-' ately shaped governor arm I93 is pivotall secured to the member I9I and upon rotation of the latter by the gear I86 upon the return movement of the lead screw, such arm I93 is thrown by centrifugal force against the inside of a stationary cup I94 fixedly secured on the pin I92. The friction intermediate the arm I93 and the cup I94 limits the speed of rotation of the lead screw which is rotating to an idle position, and this limitation on speed is effective on the other two lead screws of the particular set whose return movement is being retarded.'
